Form, fit and function replacement for Advance Hiflex HI-750 / HI-1000 series.

  • 85V – 264VAC operation
  • Signals and sequencing as per original Hiflex
  • Stud output terminals for easy connection
  • Complete transparency to end user


The original Hiflex HI-750 and HI-1000 series were manufactured by Advance Power at their Bishop’s Stortford site from the early eighties to the mid nineties. They were designed as a multi output AC-DC converter, constructed from a series of interconnected sub-assemblies – these being an RFI filter, Motherboard, Inverter board, Signals and Sequencing boards and auxiliary outputs. The original Hiflex was relatively unique in that it offered a variety of signals options including the ability to sequence the outputs up and down.
This product has been successfully trialled by both the US Navy and several airports worldwide and is accepted as a suitable replacement for HI-750 / HI-1000.
